Preserve Your Dream with Sashco Log Home Solutions 4-Step System

Whether you’re finally building your dream home or just keeping it looking sharp, Sashco has the log home solutions you’ll need. Like you, we share a passion for log homes and have spent years perfecting our products to make it easy for you to build and maintain your log or wood home. What makes log homes so charming and unique is also what gives them special challenges; irregularly shaped logs, constant expansion/contraction, susceptibility to damage from insects and harsh climates–these are just a few of the issues log home owners need to manage. Sashco log home solutions are specifically designed to address each step of the process when it comes to building and maintaining your home.

Step 1 - Prepare

CPR® Wood Cleaner and Brightener cleans and brightens bare logs and wood, and restores luster and vibrancy when used for routine maintenance. It’s a gentle log and wood home cleaner whose oxygenated bleach formula won’t weaken wood fibers while effectively killing mold, mildew and fungus, and removing dirt, dust, pollen and other surface contaminants. Use in conjunction with power washing or media blasting to perfectly prepare wood surfaces before staining. CPR breathes life into your wood, with no awkward mouth-to-mouth resuscitation necessary.

Media blasting makes removing stain from log and wood structures easier and faster than ever. Because it uses only dry media, no water is forced into the wood. Dry time is eliminated, risk of rot, mold and mildew is reduced, and stains, chinking and caulking can be applied immediately afterwards. Stop playing the waiting game and get prep done faster.

Sashco’s Kernel® Media Blaster is specifically for media blasting log and wood homes, and works with both crushed glass and corn cob media, both of which are environmentally-friendly and gentle on wood.

Crushed glass media works like millions of tiny surgical steel blades, making precise and quick work of removing both fresh and old coatings and stains, as well as UV-damaged wood. It leaves the healthy wood underneath intact and creates a lightly textured surface for improved stain adhesion and longevity. Finish sanding can be done afterwards to reduce wood texturing, but is not necessary.

Corn cob media also works to remove old coatings and stains, as well as UV-damaged wood. It keeps the healthy wood underneath intact, and when followed by finish sanding with Osborn® brushes or Sashco’s Buffy Pad system, leaves behind a lightly textured surface ideal for stain adhesion and longevity.

Step 2 - Preserve

Rot and beetles and termites – oh my! PeneTreat® is the inexpensive insurance every log and wood homeowner needs. When sprayed or brushed on bare wood, this borate-based log home preservative forms a protective shell to defend against rot and wood-ingesting insects. It’s easy to use and EPA-registered. PeneTreat will not affect the color of wood and is chemically compatible with all of Sashco’s stain, caulking and chinking products. It costs five times less than its glycol-based counterparts, yet does not sacrifice protection.

Cobra™ Rods borate wood preservative rods help you prevent wood rot before it starts. They are necessary only in highly exposed logs and timbers that are easily prone to moisture and insect infiltration, both of which can compromise the structural integrity of your log home. Cobra Rods prevent rot and keep wood-ingesting insects from taking up residence. Cobra Rods’ unique combination of copper and boron is potent yet safe. North American utility companies trust Cobra™ Rods to extend the life of their wooden poles. Imagine how your log and timber home will benefit!

Step 3 - Stain

Sun burned, grayed out logs and timbers don’t evoke feelings of inspiration and accomplishment like a dream home should. Transformation Stain® Log and Timber is the premium log stain you need to restore your log home and the dreams that go with it. Its exquisite color portfolio and glossy finish showcase the unique character of your logs and timbers. It’s specifically formulated to be chemically compatible with even the most difficult stains and coatings, making it the go-to product for even the toughest restoration jobs. Transformation Log and Timber log cabin stain will truly transform your home, resulting in a dream come true that you can’t wait to show off to your (distant) neighbors.

Capturing the true beauty of your log home can be a daunting task. Your logs are constantly on the move, which means your stain should move with them to maintain their beauty. Capture® Log Home Finish and Stain is here to help. It’s designed to stretch and compress as your logs move, creating a tight seal that prevents UV damage, insects and unwanted moisture from spoiling their unique beauty. In fact, Capture is so elastic, it even bridges those tiny micro-cracks that all logs get over time. Perhaps capturing beauty won’t be so elusive after all.

Step 4 - Seal

Davy Crockett’s cabin was cozy…except that it wasn’t. He spent a good amount of time plastering mortar into those joints every year. Old mortar cracks and crumbles out of the joints, allowing in wind, bugs, dust, rain and pollen. That’s why Sashco created Log Jam®, the industry standard for synthetic chinking. Its texture recreates that old-time mortar look while sealing your rustic cabin from vermin and wind alike. It stretches and won’t let go when your logs move. With Log Jam, you can keep the cozy feel and rustic look without compromise.

In the 1970s, log home owners everywhere were discovering that logs are in constant dynamic motion. They came to Sashco for help, and a few years later, Log Builder® was born. It’s the sealant specifically formulated to absorb most log movement. For over 20 years, Log Builder has been the trusted sealant included in many log home manufacturer’s packages. It’s superior elasticity creates a lasting tight seal that keeps out water, dust, bugs, and wind for a home that would make any bug snug in his rug, if only he could get in…

We’re tired of seeing weird, shiny caulk all over wood and log homes, too. So, we quit using that stuff and use Conceal® instead. Conceal is the first caulk designed specifically for wood. It’s lightly textured to simulate the natural roughness of wood and comes in seven colors designed to complement the most popular wood stain colors. The caulking disappears into the woodwork and your home is sealed from the elements. Stop staring at those funny looking caulk lines and get some Conceal.
